"""mdbook preprocessor which will help show the presentation aspect ratio.
|
||
|
|
||
|
The preprocessor adds a large red rectangle on every page. The
|
||
|
rectangle has an aspect ratio of 16 to 8.5, meaning that it is
|
||
|
slightly smaller than a standard 16/9 monitor.
|
||
|
|
||
|
The idea is that this approximates what the course participants can
|
||
|
bee at once during a class. This in turn will help you estimate when
|
||
|
the slides are too large to be seen without scrolling.
|
||
|
|
||
|
Enable it in book.toml.
